DISFENSING CGNTAINER FOR PASTE SHOE POLISH.

Application led December 13, 1927. Serial No. 239,755.

rlhis invention relates to dispensing con tainers for paste shoe polishand more par; ticularly to that type of container for paste shoe polish,wherein the contents of the container are dispensed by a piston which iscaused to travel longitudinally of t-hecylinder by a rotating screw.

An important object of the invention is to provide a construction suchthat the use of grooves or ribs upon the container wall coacting withribs or lgrooves upon the piston or its follower is eliminated.

A further and more specific object ofthe invention is to provide apiston follower for use in containers of this type which, by itscoaction with the walls of the container, is

held against4 rotation without any previouspreparation of the container.

'Ihese and other objects I attain by the construct-ion shown in theaccompanying drawing/wherein for the purpose of illustration is shown apreferred embodiment of 'my invention and wherein :f-

Figure 1 is a vertical sectional view through a paste polish applierconstructed in accordance with" my invention;

Figure 2 is a section on the line 22 of Figure 1; i

Figure 3 is a side elevation of the piston and follower removed;

Figure 4 is an eldarged plan view of the follower showing one of theguiding elements. i

Referring now more particularly to the drawing, the numeral 10 indicatesa container adapted to contain liquid polish and having at one end anapplying pad 11 and at. its opposite end a cap 12, which may be eitherpermanently secured to the container or removablyconnected therewith.Rotatably direc-ted through this cap is a shaft 13 having a collar orenlargement 14, preventing its passage through the opening of the cap.Exteriorly of the cap, the shaft-has ap-l plied thereto a nut or fingergrip 15, it maybe rot-ated Below the enlargement, the shaft is threadedand is directed through a member 16. This member has engagement with apiston 17 which, in turn, abuts the contents of the container.

The member 16 performs the functions of the ordinary follower and inaccordance with my invention, I provide upon the ends of this memberblades 17', which extend in the whereby direction of the-longitudinalaxis of the con- -VV tainer and have their outer faces sharpened andspaced apart a distance slightly greater Y,

of course, be understood that if the shaft 13 be rotated, the member -16will be advanced thereon and in its advance, will force before it thepiston acting upon the contents.

A device of this character may be ver readily produced and because ofthe fact that no particular alignment of the casing and follower isnecessary, maybe very quickly and readily assembled. As the constructionhereinbefore set forth 1s capable of a certain range of change andmodification without materially departing from the spirit of theinvention, I do not limit myself to such-specific structure eX- cept ashereinafter claimed.

`1. In a dispensing container for shoe polish and the like, a casinghaving a cap at one end, a shaft rotatable in the cap and extendinglongitudinally of the casing, means holdingthe shaft againstlongitudinal movement with relation to the cap, a piston within thecasing, a member having engagement with the piston whereby the' pistonshifts with the member as the member moves in one direct-ion, the shaftbeing threaded through the member, the member having means engaging thewall of the casing a portion of which coactswith the inner faces of thewall to form a non-perforating groove therein as the member is advancedin the casing and other portions of which operate in said groove.

2. In a dispensing container for shoe polish and the like, a casinghaving a cap at one end, a shaft rotatable in the cap and extendinglongitudinally of the casing, means holding the shaft againstlongitudinal movement with relation to the cap, a piston within thecasing, a member having engagement with the piston whereby the pistonshifts with the member as the member moves in one direction, the shaftbeing threaded through the member, the member having a blade forciblyengaging the interior wall of the casing without erforating the. same,said blade extending ongitudinallj7 of the casing.

3. In combination with a piston, of a tubular dispensing container,'afollower for the .piston having' diametrically opposed knife blades, theedges of which substantially parallel the axis of the' container and arespaced apart a distance slightly greater than the internal diameter ofthe container and less than the external diameter of the container.

' 4. The combination with a tubular dispensing container, a pistontherefor, of means i for advancing the piston cornprsinr a rotatableelement, a member engaging tbe piston advanced by rotation of theelement and portions upon the element having knife edges paralleling theaxis of the element and spaced apart a distance slightly greater thanthe diameter of the casing, lsaid portions grooving Without slittingthe` Walls of the container,

In testimony whereof I- hereunto affix my signature.
